it enables them to actually do field science. to know what rocks and soils are nearby and what they can reach or how long it might take somewhere, the use a combination of 3-d images, computer graphics, and simulations often overlaying them. these visualizations allow them to point to places, give them names, and control precisely where new photographs are taken and where the instruments are placed. so for example, they can draw a yellow box to specify where a camera should zoom in for a more detailed image. each photograph can be used like a map of an area on mars, because its location relative to the rover is precisely registered in the planning program. as we move him from panoramas used for navigating it manages about crops to the micro photographs, we can see and market up details. even small rocks and patches of soil might be named and become targets for analysis or a micro photographs. combining these planning tools in their imagination, the scientists can work as if they were on mars. jim rice, a geologist on a mission, s
